This page explains an ideal technique for creating tile sets in 3ds Max or Maya.

Tile Set

A Tile Set is any number of assets designed in a semi-modular fashion that can be assembled by world builders in HeroEngine.

A tile set can be interior or exterior rooms or it can be fencing or a scaffolding system. The possibilities are endless.

Considerations

When designing pieces that are intended to fit together seamlessly, there are many technical problems to consider.

Example Process

The ideal way to construct tile set pieces is to start with a grid. The grid needs to be defined based on what you are working on. Since .1=1 meter, we found that .25 is a good starting point for building an interior room Tile Set. This works with rotation as well. Until recently, it was only possible to snap an asset 90 degrees, but now you can choose whatever you wish. 15 degree rotational snap works out well because it covers, 30-45-60-and 90, also the smaller increment gives some visual feedback to what you are doing.

Although this tutorial is done in 3ds Max, it directly translates to Maya.

Now that the grid is planned out, modeling may proceed. The best way to go about this is to figure out how the pieces will connect together. Generally this means a door. You want to build it with the inside connection border precisely at 0 on the y axis. Spend some time on this shape and get it the way you want. It will be the template for everything else that connects to it. If you can, it may be a good idea to UV and texture it to reduce doing the same shape over and over later on.


Once you are happy with your portal, duplicate it (as an instance if you intend to modify the portal so that both change accordingly) and flip it 180. Make sure your vertices are lined up perfectly.

Duplicate each door and make a network of them at 5m increments.

Now take them all, duplicate, and rotate them 90 degrees. At first glance this may seem counter-intuitive. But what you've just done is mark the doorway for every room you are about to build with that connector piece. You can make your templates with as many or few portals as you think you'll need. It's up to you and your needs.

Save out your template so you can always go back to it. Get a new file going with your template as a base. Delete portals until you get 2-4 that will form the edges of a room.

Once some portals are selected, attach the geometry and simply connect the interior walls, floor, and ceiling. After it is all connected, and there is a room-like shape, move the pivot point to (0,0,0) or anywhere that you would like the pivot to be. Sometime an offset pivot works better, it just depends on what you want.

Embedded Asset Settings

This is now done in Hero Asset Tools. This used to be done manually through the user defined property in 3dsMax and the Notes Property in Maya.

The format for this is as follows in both programs, though you should never have to edit this by hand, this is purely for knowledge of what happens under the hood.

GridSnap=.25

RotationalSnap=15

Occluder=true


Aside from texturing the model, it is ready. HeroEngine will now recognize these settings and snap your tile set together.


Multi Angle Set

Let's say we want to make a Y shaped room.

Duplicate 2 Instance 120 degrees each direction.

Just like in the previous demo, connect the walls, floor, and ceiling. It is strongly advised to make a more interesting shape than just what is being shown here.
